Intelligent Energy Competency Multipath Routing in WANET

In modern era, the use of wireless ad hoc network (WANET) has been increasing rapidly. Every nodes of WANET are directly communicated with each other to share information within the range. This network is dynamic and infrastructure-less, so topology of this network can change very frequently. WANET nodes are powered by battery with limited capacity and due to this reason sometime nodes are fail to transmit data packet from source to destination. The present paper proposes a routing protocol, named Intelligent Energy Competency Multipath routing protocol (IECM) for WANET. The basic idea of IECM is to select energy efficient multipath which reduces energy consumption of ad hoc nodes based on intelligent method. This method is mainly used to extend the lifetime of WANET by specifying a different intelligent scale to each route. This scaling system evaluated by three phase intelligent initiation phase, second path evaluation phase and third multipath route selection phase. Based on the comprehensive simulation of IECM using MATLAB and NS2 and comparative study of same with other existing protocols, it is observed that proposed routing protocol contributes to the performance improvements in terms of energy competency.
